WINDOW.

SPECIFICATION forming part of Letters Patent No. 529,134, dated November13,1894. Application filed June 9, 1894. Seria1No. 514,040. (No model.)

To coZ Z whom it may concern:

Be it known that I, JACOB ORT, a citizen of the United States, residingat Wahoo, in the a specification.

My invention relates'to improvements in window sashes and their casings,of the class in which the window is opened and closed by raising andlowering the sash in guides on the casing.

My object is to provide improvements in the construction of windows andcasings of the class described, which shall cause the sashes to movewith comparativelylittle friction in raising and lowering and at thesame time prevent their rattling; and cause them to be dust and draftexcluding.

A The drawing shows a broken section, on two horizontal planes atdifferent elevations, of the upper and lower sashes and easing at oneside of the window, and showing my improvements in their preferred form.

A is the window casing; B, the lower sash, and O the upper sash. Formingpart of the casing is the blind-stop or outer guide-rail A.

D is a parting-strip or stop, forming with the outer rail A the guidefor the upper sash, and which is set into a groove 15 in the jamb of thecasing, in the usual manner; and E is the inner window-stop.

In the preferred construction the side-rails of each sash are providedon their inner faces near the edges with,preferably, rectangular groovess. The stop E is formed with a tongue portion 1' on its inner forwardside, and an inner beveled surface 2". The stop E fits at its tongueportion 0" in a shallow groove t in the casing, being fastened in placepreferably with nails y, and it flares at its surface r in the backwarddirection, away from the adjacent surface of the casing.

F is a metal guide or weather strip, angular in cross-section to extendacross the rear edge of the stop E and overlap the surface r at which itis attached by means, preferably, of screws :20. At its free edge thestrip is shaped to form alongitudinal tongue or boxportion q presentinga straight side-surface q, a straight rear-surface g and an inclinedside-surface The tongue q extends into the groove 5 of the sash-railatthe outer side of the latter; and fitting in the groove 3 is aretaining strip p of wood, soft vulcanized rubber, or the like, havingan inclined edge 19 which fits the inclined surface (1 The strip 19 maybe fastened in place with screws 00, as shown.

It is to be understood that the stop E and sash rail at the oppositeside of the window are provided with a guide or weather-strip F andretaining-strip p, the same as at the side shown. The inwardly yieldingtendency of the stops E, and of the strips p, if of rubber or the like,will prevent binding of the lower sash, at the tongues q; and the degreeof pressure of the retaining strips p against the surfaces of thetongues q, may be increased or diminished as desired, by tightening orloosening the screws w. The upper sash G is also provided on its innerface near the edges of its side-rails with grooves s; and on theparting-stops D are metal guide pieces F having tongues q formed withthe surfaces (1' q and inclined surface (1 the same as the guide piecesF. The only difierence between the guide-pieces F and F is that whilethe former are bent to extend around the under inner corners of thewindow-stops, the latter are flat and fit the outer surfaces of theparting-stops, to which they are secured by means of screws 41:. In thegrooves s of the upper sash are placed retaining strips p, the same asin the lower sash.

The tongues q should'fit closely in the sockets formed by the grooves sand retaining strips p, but not so closely as to interfere with theready sliding of the sashes; and the construction renders the jointsbetween the sashes and the casing and between the sash meeting-railsabsolutely dust proof and draft excluding. If the sashes should swell,the screws 00 which hold the retaining strips in place, may be loosenedto cause the strips to bear more gently against the tongues What I claimas new, and desire to secure by Letters Patent, is-

1. In a window, a sash-frame having window-stops, metallicweather-strips F, on the stops, provided with tongues (1 formed withinclined faces 5?, grooves s, in the faces of the provided with tonguesq, having inclined 10 faces and which extend into the sashgrooves s, andretaining-stripsp in the grooves 3 having inclined faces to engage thefaces 41 of the tongues, substantially as described.
